On two-dimensional finite-gap potential Schrödinger and Dirac operators with singular spectral curves
I. A. Taimanov Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences
Abstract:
We describe a wide class of two-dimensional potential Schrödinger and Dirac operators which are finite-gap at the zero energy level and whose spectral curves at this level are singular, in particular may have $n$-multiple points with $n\geqslant3$.
Keywords:
Schrödinger operator, Dirac operator, spectral curve, finite-gap integration.
